Saitama's POV

The B-Class hero Saitama stood there impatiently as the Dragon Class being known as Black Sperm continued droning on about himself dying.

"9 trillion 999 billion 999 million 999 thousand 999 of me disappearing into nothingness. On the other hand, I am also happy from the depth of my heart."

With a flash, a golden coloured version of Black Sperm was created.

"The 10 trillion merge… my true self makes its deb-"

"That's too long! Shorten it to 20 words or less!" Pulling back his fist, the Caped Baldy punched Golden Sperm in frustration.

His fist impacted the Mysterious Being, causing a huge shockwave which demolished several nearby buildings and cleared the sky of clouds. The golden body flew a few hundred feet away and flopped to the ground lifelessly, its body almost torn apart by the force of the punch.

Several horrified gasps came from beside him.

"That's impossible…"

The Caped Baldy turned to see the last few dozen cells of the Being standing there, looking terrified, surrounded by thousands of his dead cells.

"Is-is this some kind of joke? This is a B-Class hero?"

"No." Another sperm argued, although his voice had a slight tremor. "This is obviously an S-Class in disguise. The Hero Association must be hiding his existence.

"Then what should we do?"

"I say we disperse. There's still 60 of us left, he can't catch us all if we head in separate directions. We'll regroup elsewhere and rebuild our str-"

"Atomic Slash!"

The last few dozen cells were sliced apart in a flurry of sword slices. The pieces lay suspended in the air for a brief moment before falling, revealing a middle aged man in Japanese robes with a sword.

The man's eyebrows furrowed. "You're that B-class hero that Silverfang praised at the meeting."

"Oh! You're that middle-aged hero dude."

The swordsman's eyelid twitched. "I told you I'm only 37." He looked over the carnage. "You did this by yourself?"

"Mm."

"Not bad, you do have potential. The Hero Association must have stated its Threat level wrong though, it couldn't have been a Drag-" his face suddenly hardened, and he looked at Saitama with suspicion.

"Tell me, what were you doing yesterd-"

Ring ring!

The S-Class sheathed his sword and reached into his robes, pulling out a cell phone. "Yes?" Saitama could faintly hear someone yelling something about Demon Class and vampires on the other end.

"Alright." The samurai looked back at him, his eyes conflicted. "Saitama is it? You can leave now, my disciples and I will handle the rest."

"Ok." The B-Class turned around and began walking back to his apartment.

"I wonder if Genos bought Teriyaki sauce."

Geno's POV

The blonde cyborg raced down the streets, frustrated. The Hero Association had provided no information about the supposed threat other than that it was threatening multiple locations at once, and that it was a Dragon Level Threat. He had passed several ruined streets so far but had not seen any Mysterious Beings.

As he shot down another street and rounded a corner he spotted a familiar heat signature, casually walking down the street.

"Sensei!"

"Ah! Genos!" The B-Class looked up cheerfully. "Where have you been? Also, did you get the teriyaki sauce?"

"Sorry Sensei, I was at the S-Class meeting, and came back here when it was reported that there was a Dragon level Threat. I am on my way to nullify it as we sp-"

"Attention citizens, the Threat has been dealt with. You are now free to leave the shelters."

"..."

"..."

"I'll go get the teriyaki sauce now."

"Ok." His Sensei yawned. "I'll go get the cabbages for tonight's dinner. We'll meet back home."

"Yes Sensei!" The blonde Cyborg pulled back his arms, activating rocket thrusts in his shoulders and feet. With a burst of flames they launched him hundreds of feet into the air, and he shot off towards the supermarket.

Several minutes of intense bargaining later, he had secured the teriyaki sauce at minimal cost, narrowly snatching it from the grasp of several other shoppers. His Mission complete, the S-Class flew back to his home.

As he touched down near the doorway, he observed that the door was unlocked. Entering, he was greeted by the sight of his Sensei sprawled haphazardly on his futon, and a large plastic bag of cabbage dropped clumsily beside it.

Moving quietly as so not to wake him up, Genos picked up the bag and walked into the kitchen. A compartment in his wrist opened, and out popped a peeler. After peeling and chopping up the carrots and potatoes, he tossed them into a pot of lightly boiling water. Once they were soft, he would fry them with the teriyaki sauce.

From behind him he heard shuffling and the sound of clothes ruffling, followed by the sound of footsteps.

"Ah Sensei you're awake. Shall I-"

He heard the sound of his Master putting on his boots, before twisting the doorknob and opening the door of their house.

"Sensei are you going out?"

The door slammed shut.

"Sensei?"

But his Master was already gone.

Sitch's POV

"Sir!" The Minister Office of Justice looked over at one of his subordinates, who was frantically pointing at his screen. "One of Metal Knight's drones just spotted something! We have confirmed footage of the suspected Mysterious Being fighting multiple heroes!"

"Where is it?"

"We have pinpointed its location to an abandoned part of Z-City sir!"

"Notify all available heroes to converge on that location at once!"

Atomic Samurai's POV

The S-Class hero raced down the streets, his sword gripped tightly in his hands, his two disciples racing alongside him. As he ran, the swordsmaster cursed himself internally.

Less than an hour ago he had been mere feet away from the Hero Hunter, with easy range of his swords. Rather than recognising him immediately, he had let the Hunter go.

Now not only had he taken down more heroes, but he was no doubt in a more combat ready state. The only good thing was that he was probably tired out from his hero hunting.

I should have sliced him in half when I had the chance.

He growled in determination, his hand tightening on the hilt. Don't worry Iai, I'll avenge you. I shall stain my sword with the blood of that darned Caped Baldy.

As he rounded a corner, he almost collided with an elderly man slowly walking across the street.

"Move out of the- oh ho, Silverfang!"

"Atomic Samurai." The S-Class Rank 3 greeted back. "Where are you going in such a hurry?"

"I'm off to kill the Being that has been hunting down heroes recently. You here to do the same?"

"Yes, but I'm also here for another reason. My Brother sent over too much Wagyu Beef, so I want to invite Saitama and Genos over to help me finish it. Would you and your disciples like to join us?"

"Saitama? You mean B-Class Caped Baldy?"

"That is his hero name, yes."

"I'd advise you not to waste such prime meat on him, Silverfang. He's the Being we've been ordered to put down today."

Silverfang shook his head. "You must have the wrong guy, Saitama would never do anything like that."

He blinked in surprise. "No?"

"No. A lookalike perhaps, or maybe someone is imitating him. It can't be Saitama doing the recent spate of hero hunting."

Bushidrill stepped forward. "Are you sure?"

"No, I am sure of it." The old man looked at the sky. "Goodness, it's getting late. Shall we?"

"Master." Bushidrill stepped forward. "Please don't be distracted from our task. Whether it is Caped Baldy or not, the Being is currently running free, we must cut it down now."

Their Master clenched his jaw, a conflicted yet thoughtful expression flickering over his normally proudly determined features.

"It can't be Saitama eh?"

Saitama's POV

When Saitama had opened his eyes, he had expected to be at home, staring at the ceiling of his house. He had not expected to be standing on the streets, several B and C-Class heroes lying unconscious in front of him.

"What happened here?"

"What the heck do you mean what happened?" Saitama looked down to see a hero with a red nose in shattered armor. "You did this!"

"I did?"

"Of course you d-ack!" The hero passed out, a thin stream of saliva flowing over his bruised face.

I must say I'm quite impressed.

Saitama frowned. "Who said that?"

My name is-

"I don't care what your name is but what are you doing in my head?"

Nothing of importance to you, except that-

"Ok." With that he began to pick up the bodies of the heros in front of him.

You don't even want to listen to my explanations?

"You just said that it wasn't important to me."

"Stop right there!"

The Baldy turned around to see five heroes standing in dramatic poses behind him. There was three people in tank tops, a guy with a fancy moustache and fencing sword as well as a man in a hat and a hoodie that said "golden ball".

"Oh. Can you guys help me with this? I can't carry them all to hospi-"

"Backing out now eh?" The man in the hat pulled out a slingshot, and let loose a barrage of small golden balls.

Saitama easily dodged the balls, causing the man's eyes to widen. "Be careful! You almost tore my clothes with that."

"So you're the one who took out my little bro." One of the tank toppers, dressed in a plain blue tank top, stepped forward.

Saitama's forehead furrowed. "Little bro?"

Another one dressed in a tank top adorned with leaves, stepped forward. "Feigning ignorance now that you're staring down Tanktop Master?"

The last tanktopper, who was dressed in a yellow Tanktop adorned with black stripes, cracked his knuckles. "Today, you'll pay for beating up Tanktop Blackhole!"

"Tanktop Blow!" The blue tanktopper spun around and slammed his fist into the ground, sending a ripple through the concrete, causing Saitama to wobble slightly where he stood.

"Isn't that a little rude? The city's wrecked enough already…"

"Tanktop Punch!"

The yellow tanktopper cheered. "The versatility of the tank top doubles the for-" but his yell was cut short as the S-Class tanktopper fist impacted Saitama's face. A soft crack was heard, and the tanktopper cried out and stumbled back.

"M-Master? Are you ok?"

"Let me take care of him!" The man in the suit pulled out a handkerchief from his suit pocket, which transformed into a fencing sword. The thin blade immediately folded in upon itself like a spring.

"Tomboy!" The sword unfurled, shooting towards him. Saitama casually turned to the side, watching the blade punch through a telephone pole before going back to its owner.

"Oi, stop that." But the man simply leapt back, the blade coiling again as he did, and unleashed the sword again. The Caped Baldy sighed and tilted his head slightly, before biting down on the blade, causing it to shatter.

"What do you think you're doing?" All the heroes looked up to see the S-Class ranked 16 hero Genos hovering dramatically above them.

"It's good that you're here Demon Cyborg, you can help us capture him." But to their surprise the Cyborg landed in front of them, cracking the ground as he did, and aimed his weapons at them.

"Why are you threatening Saitama Sensei." The cyborg's tone implied that it wasn't a question, but a warning.

The one with the moustache blinked in surprise. "Sensei? You're his student?"

"Correct."

"Why is a S-Class under a B-Class?"

"We're getting off topic." The blue tank topper stepped forward, still cradling his wrist. "Demon Cyborg, your Sensei is responsible for severely injuring over 40 heroes, including a fellow S-Class."

"Impossible!"

"Look around you. In the past hour alone he has defeated all these heroes."

"Leave now, or I won't forgive you for wasting Sensei's time…"

Saitama sighed. Knowing Genos, he wouldn't let them off until he got a full apology from them, and seeing how angry they were at him that might take hours. And he still had these wounded heroes to bring to hospital. He sighed again, rubbing his stomach. Man I'm starving.

Out of the corner of his eye, he spotted what looked like a giant bird crouched on the roof of the building. When it realized that it had been spotted it immediately spread its wings and flew away.
